Abstract

A time-of-flight neutron diffraction experiment was undertaken on a powder sample of orthorhombic ZrO₂ synthesized at 600°C and 6GPa for 30min. The Rietveld analysis for the diffraction data shows that the space group of this phase is Pbca. The refined lattice parameters are a₀=1.00861, b₀=0.52615, and c₀=0.50910nm.
